p7zip is the Unix command-line port of 7-Zip, a file archiver that
handles the 7z format which features very high compression ratios.
p7zip provides:
- /usr/bin/7zr
a standalone minimal version of the 7-zip tool that only handles
7z, LZMA and XZ archives. 7z compression is 30-50% better than ZIP
compression.
- /usr/bin/p7zip
a gzip-like wrapper around 7zr.
p7zip can be used with popular compression interfaces (such as File
Roller or Nautilus).
Another package, p7zip-full, provides 7z and 7za which support more
compression formats.
